Description

technical field [0001] The present invention relates to a method and device for preventing whipping of optical fiber by screening and rewinding, which relates to a method and device for preventing whipping of the optical fiber at the receiving end after abnormal fiber cutting during optical fiber screening and rewinding in optical fiber production. device. Background technique [0002] In the production of optical fiber wire drawing, the screening and rewinding machine process of optical fiber will automatically stop winding after the winding end is full of optical fiber under normal circumstances, and the optical fiber between the small reel and the large reel remains intact. When the fiber is not fully wound, the fiber is broken. After the fiber is cut, the fiber at the take-up end will continue to move in the direction of rotation under the action of inertia, and the end will be directly hit on the collected fiber, causing the fiber to be broken.

Problems solved by technology

[0002] In the production of optical fiber wire drawing, the screening and rewinding machine process of optical fiber will automatically stop winding after the winding end is full of optical fiber under normal circumstances, and the optical fiber between the small reel and the large reel remains intact. When the fiber is not fully wound, the fiber is broken. After the fiber is cut, the fiber at the take-up end will continue to move in the direction of rotation under the action of inertia, and the end will be directly hit on the collected fiber, causing the fiber to be broken. The optical fiber is damaged by collision, which affects the quality of the optical fiber

[0003] In order to ensure the quality of the produced optical fiber, it is necessary to remove the damaged optical fiber. This process will generate a certain amount of optical fiber scrap, resulting in unnecessary waste. At the same time, it will increase the workload of equipment and personnel, and increase the cost of optical fiber manufacturing.

[0004] At present, the protective cover is usually used in the industry, which can reduce the swing amplitude of the abnormal fiber breakage to a certain extent, but in the process of screening and rewinding, it is still inevitable that the optical fiber will bounce back to the optical fiber disk after colliding with the protective cover. , resulting in fiber whipping, resulting in fiber removal loss

[0005] Severe optical fiber whipping will lead to direct breakage of the optical fiber, resulting in multiple optical fibers on the small disk. Depending on the degree, there will be a certain difference in the processing time, which wastes a lot of time and labor.
